QT interval represents the ventricular depolarization and repolarization. Its accurate measurement is critical since prolonged QT can lead to sudden cardiac death. QT is affected by heart rate and is corrected to QTc via several formulae. QTc is commonly calculated on the ECG and not the 24-h Holter.

24 小时动态心电图上的 QTc 间隔:信任还是不信任?

QT间期代表心室除极和复极。其准确测量至关重要,因为延长 QT 会导致心源性猝死。QT 受心率影响,并通过几个公式校正为 QTc。QTc 通常在 ECG 而非 24 小时动态心电图上计算。
